Page 20 - ... the catches of the gauges were due to the irregularities of horizontal distribution of the strength of the wind as influenced by the surroundings. In other words instead of studying the geographical or horizontal distribution of the total annual rainfall it was safe to assume that that had been uniform for each year over this small area, and that we are studying simply the horizontal distribution of a deficiency in catch or a rain-gauge error due to very local winds at the mouths of the gauges..

Page 46 - Alleghanies, upon which falls the heaviest rains of spring at a time when the normal rise of the Lower Mississippi brings the river almost to the danger line from Cairo to the Gulf. In the greatest floods we also find that heavy rainfall over the great swamp region that extends along the Mississippi from the mouth of the Ohio to the Gulf of Mexico is an important factor. Third in importance as a factor in producing floods is the Upper Mississippi, which, while never discharging a volume sufficient...
Page 75 - The water, after leaving the main river, passed into the St. Francis Basin, through which runs the Little and St. Francis rivers; through these channels it again found its way to the Mississippi at a point about 12 miles north of Helena, Ark. The effect of leveeing the west bank of the Mississippi, in front of the St. Francis bottom, is to compel the water to pass down the Mississippi, from Cairo to Helena. In the following table a comparison is made of several earlier floods with that of this year....

Hellmann's records show that the geographical irregularities in the catch of his gauges is really least in summer and greatest in winter, thus confirming our convictions that on the average of the year the precipitation is uniformly distributed and the variations in catch depend on the geographical distribution of the wind at the gauges during the fall of rain and snow. The eleven gauges...

He was a most voluminous writer ; but the works which have immortalized his name are his HEXAPLA, or Collation of the Septuagint version, which Father Montfaucon supposes must originally have made fifty volumes ; and his Vindication of Christianity against...
Page 20 - ... 424 518 336 140 and the irregularities in horizontal distribution are presumptively greatest at that time. During the winter the extended layers of clouds give us no a priori reason to expect large irregularities in the geographical distribution of snow fall and rain. Hellmann's records show that the geographical irregularities in the catch of his gauges is really least in summer and greatest in winter, thus confirming our convictions that on the average of the year the precipitation...
